ow do you check for inequality in an if statement?Answer areax =! yx == yx != yx < y

To check for inequality in an if statement, you can use comparison operators. Here’s a breakdown of the options you've provided:

1. x =! y: This is a common mistake. The correct notation for checking inequality is x != y, where != means "not equal to". The = operator is for assignment, not comparison.

2. x == y: This statement checks for equality, not inequality. It returns True if x is equal to y.

3. x != y: This is the correct operator to check if x is not equal to y. If x and y differ, the statement evaluates to True.

4. x < y: This checks if x is less than y, which is not an inequality check per se, but is a part of comparison operators that can reveal inequalities.

Thus, the primary way to check for inequality is using the != operator. For example:

if x != y:
    print("x is not equal to y")

This will execute the block of code if x and y are not equal.
